I don't think its a wastage, it really is a different exprience
between facing dull blue color interior and facing a bright yellow
color interior, it simply brightens up your day especially in the
morning. TIBS is another company who regular ensures their buses
are in good shape, I guess ah if they dint Merge, your UDs or Mercs
would have looked nicer.
If they dint refurbish their Mk2s or O.405s, then we get a lot of
complains by commuters saying the hot SBS buses, no air con and
whatever shit.
